How can a heat exchanger be designed for a specific industrial process involving the heating and cooling of a liquid stream with a flow rate of 500L/min and a specific heat capacity of 4.2 kJ/kg K? The temperature of the hot and cold streams are 120°C and 25°C respectively, and the process requires a heat transfer rate of at least 200 kW. What should be the surface area and overall heat transfer coefficient of the heat exchanger to meet the process requirements?
